Catherine Zeta-Jones Enters Treatment Center

“Catherine’s stint in the treatment center is a proactive measure. It’s maintenance,” a source tells TMZ.

Catherine, 43, completed a stint at a treatment center in 2011. At the time, her rep said, “[Catherine] made the decision to check in to a mental health facility for a brief stay to treat her Bipolar II disorder.”

In December 2012, Catherine told Elizabeth Vargas that she’s sick of talking about her bipolar disorder. In the Dec. 7 interview on Good Morning America, Catherine snapped back at the interviewer and said, “You know what? I’m sick of talking about [my bipolar disorder] because I never wanted to be the poster child for this. I never wanted this to come out publicly. It came out.”

She continued, “I dealt with it the best way I could. It was just saying, hey, I’m Bipolar. Everyone has things going on and we deal with them the best we can. We can’t jump from the rooftop shouting, ‘I have this, look at me, victim’ — we all have issues in life. I’m really happy that I have great friends, great support and that’s all you can do.”

Catherine’s rep tells HollywoodLife.com, “Catherine has pro actively checked into a health care facility. Previously Catherine has said that she is committed to periodic care in order to manage her health in an optimum manner.”
